Question

(y=mx+b)
X, Y
0,9
2,5
4,1
6,-3

Answer 1

To find the values of m and b in the equation y = mx + b, we can use the given points (x, y) and substitute them into the equation.

Using the first point (0,9):
9 = m(0) + b
9 = 0 + b
b = 9

Using the second point (2,5):
5 = m(2) + 9
5 = 2m + 9
-4 = 2m
m = -2

Finally, substituting the values of m and b into the equation gives:
y = -2x + 9
